Multi-phase shampoo composition with an aesthetic design

ABSTRACT

A container configured to hold a multiphase shampoo composition. The multiphase shampoo composition has a cleansing phase containing a detersive surfactant and a benefit phase containing a gel network. The cleansing phase and benefit phase are visually discrete phases, in physical contact, and form an aesthetic design suspended across at least a portion of the container.

FIELD OF THE INVENTION

The present invention relates to a container with a stable multiphaseshampoo composition with an aesthetic design, specifically a multiphasecomposition with a cleansing phase containing a detersive surfactant anda discrete benefit phase.

BACKGROUND OF THE INVENTION

Some consumers want a shampoo composition that effectively cleans thehair, while also providing excellent conditioning, which can includegood wet and dry feel, while also having a striking appearance on thestore shelf and/or webpage/app.

Today, there are clear shampoos that can signal superior cleaning butgenerally do not appear to provide excellent conditioning and creamyshampoos that can signal excellent conditioning but generally do notappear to provide excellent cleaning. Consequently, there is consumerinterest in a multiphase shampoo with stable discrete phases including acleansing phase and a benefit phase, which can provide hair and scalpbenefits including superior conditioning.

However, it can difficult to maintain discrete phases in a shampoocomposition throughout the shelf life of the shampoo composition, whichcan include shipping, handling, and storage at home, storage facility,and/or store shelves, and repeated dispensing. Shampoo compositions,especially those that are known to provide good conditioning, generallycontain charged ingredients including surfactants and polymers that caninteract with each other and/or other formulation ingredients, which candiminish the shampoo's rheology, stability, efficacy, and/or userexperience. These issues are compounded when the benefit phase forms anaesthetic design because even slight phase disruption or conversion willbe noticeable to consumers and instead of having a striking appearancethat connotates quality, the product will appear mediocre.

Therefore, there is a need for stable multiphase shampoo compositionthat delivers excellent cleansing and conditioning where the phases forman eye-catching aesthetic design.

DETAILED DESCRIPTION OF THE INVENTION

Some consumers want a shampoo composition that effectively cleans thehair while providing additional consumer benefits, such as improved wetand dry feel that can be provided by conditioning ingredients, and has astriking appearance at the store shelf and/or webpage/app. FIGS. 1 and 2are photographs of multiphase shampoo compositions that have anaesthetic design, specifically a swirl, suspended throughout. In FIGS. 1and 2 , the two-phases are stable, discrete, and packaged in physicalcontact with each other. The two-phases can include cleansing phase 1,1′ and benefit phase 2, 2′.

The cleansing phase can contain a surfactant system that can include oneor more detersive surfactants and a structurant. In some examples, thecleansing phase can be visibly clear with a light transmission greaterthan 60%, alternatively greater than 80% as measured by the LightTransmittance Method described hereafter. In other examples, thecleansing phase can appear hazy, cloudy, or even opaque. The cleansingphase can be colored, colorless, or combinations thereof.

The benefit phase can be opaque or translucent and can be suspendedacross the entire shampoo composition or one or more portions of theshampoo composition. The benefit phase can help the shampoo appear moreconditioning without sacrificing the clarity of the cleansing phasewhile also providing a shampoo composition that appears different andexciting. The benefit phase can contain a gel network, which refers to alamellar or vesicular solid crystalline phase that can contain at leastone fatty alcohol, at least one surfactant, and water and/or othersuitable solvents. The benefit phase can be uniform, non-uniform, or acombination thereof. The benefit phase can be any suitable shape(s) toform an aesthetic design including regular and/or irregular patternsincluding swirls, as show in FIGS. 1 and 2 . The shape can form anaesthetic design that resembles the following non-limiting examples:bubbles, stripes, cross-hatching, zig-zag, floral, petal, herringbone,marbled, rectilinear, interrupted stripes, checked, mottled, veined,clustered, speckled, spotted, ribbons, helical, swirled, arrayed,variegated, waved, spiral, twisted, curved, streaks, laced, basketweaved, sinusoidal including but not limited to meander, andcombinations thereof.

In addition to a gel network, the benefit phase can contain additionalingredients, including ingredients that could make the cleansing phasecloudy or opaque such as conditioning ingredients (e.g. cationicdeposition polymer, silicones with an average particle size greater than30 nm, crosslinked silicone elastomers), anti-dandruff actives (e.g.zinc pyrithione), aesthetic ingredients (e.g. mica), and combinationsthereof. The additional ingredients can be carefully selected (e.g. theingredient may not have too high a salt concentration) because it maydisrupt the gel networks, causing the gel network structure to collapse,forcing the solvent out, which can destroy the aesthetic pattern andmake the shampoo composition appear less effective.

The proper rheology, which can include viscosity, yield stress and/orshear stress, of the cleansing phase and the benefit phase can bebalanced so the product is consumer acceptable, while maintainingsuspended discrete stable phases. The cleansing phase can have a yieldstress, Herschel-Bulkley @ shear rate 10⁻² to 10⁻⁴ Pa of from about 0.01to about 20 Pa, alternatively from about 0.01 to about 10 Pa,alternatively from about 0.01 to about 5 dPa. The yield stress ismeasured at 26.7° C. by flow sweep at a shear rate 100 to 1.0e−4 1/susing Discovery Hybrid Rheometer (DHR-3) available from TA Instruments.To apply the Hershel-Bulkley model, the TA software to fit the model inthe log space at a shear rate from 10⁻² to 10⁻⁴ s⁻¹ is used. Thegeometry used to measure the yield stress and viscosity of the cleansingphase is a 60 mm 2° aluminum cone (with a Peltier steel plate). Thegeometry should be run at the gap specified by the manufacturer for thegeometry. Trimming the sample during the initial conditioning step instep 1 is recommended to ensure data integrity and reproducibility.Torque map the geometry prior to running the yield stress or shearstress methods when the instrument+geometry is out of calibration. Theversion of Trios software used to generate the rheology data herein isTRIOS 5.1.1

The cleansing phase and/or the benefit phase can have a viscosity at @ 2s−1 Pa·s of from about 0.01 to about 15. The cleansing phase can have aviscosity @ 100 s−1 Pa·s of from about 0.1 to about 4 Pa·s,alternatively from about 0.1 to about 2 Pa·s, alternatively from about0.1 to about 1 Pa·s.

The benefit phase can have a shear stress of about 100 Pa to about 300Pa at a shear rate of 950 s⁻¹, alternatively about 130 Pa to about 250Pa at a shear rate of 950 s⁻¹, and alternatively about 160 Pa to about225 Pa at a shear rate of 950 s⁻¹. The shear stress is measured at 25°C. by flow ramp at an initial shear rate 0.1 to final 1100 1/s usingDiscovery Hybrid Rheometer (DHR-3) available from TA Instruments. Thegeometry used to measure the yields and viscosity of the cleansing phaseis a 60 mm 2° aluminum cone (with a Peltier steel plate).

The weight ratio of cleansing phase to benefit phase can be from about1:4 to about 99:1, alternatively from about 1:1 to about 98:2,alternatively about 3:1 to about 97:3, alternatively from about 4:1 toabout 95:5, alternatively from about 4:1 to about 20:1, alternativelyfrom about 4:1 to about 10:1, alternatively from about 4:1 to about 9:1,alternatively from about 4:1 to about 6:1.

In some examples, the shampoo composition can be dispensed from a pumpbottle and the ratio of cleansing phase to benefit phase can vary byless than 20% each pump, alternatively less than 15% each pump, andalternatively less than 10% each pump when dispensing the first ⅔ of thebottle contents, alternatively the first 80%, and alternatively thefirst 90%.

The shampoo composition can provide a mean final rinse friction lessthan 2000 gf, alternatively less than 1750 gf, alternatively less than1700 gf, alternatively less than 1650 gf, and alternatively less than1600 gf when dispensing from 10% to 55% by volume. The mean final rinsefriction can be determined using the Hair Wet Feel Friction Measurementmethod described herein.

The shampoo composition can be sold, stored, and dispensed from abottle. The bottle can be transparent or translucent so the user can seethe design suspended in the product from the exterior of bottle.Alternatively, the bottle can be opaque and can optionally have one ormore transparent or opaque windows where the consumer can see thesuspended design. The shampoo composition can be dispensed from thebottle by squeezing. Alternatively, the shampoo composition can bedispensed with a pump, which may be preferred in some examples becausethe pump may reduce disruption of the benefit phase throughout the useof the entire bottle.

The shampoo composition can be in a bottle that is substantially free ofa headspace and/or visually discernable air bubbles, to help maintainthe design before use. It was found that air bubbles, especially largeair bubbles, and a headspace can destroy a suspended aesthetic designduring shipping and handling. A headspace can be eliminated by eitheroverfilling the bottle or using an insert that can have a snap fit withthe neck of the bottle to consume the headspace volume, an example of aninsert is described in patent application No. 62/977,140, herebyincorporated herein by reference.

However, it can be difficult to eliminate all the air that is trapped inthe shampoo product. After filling, shampoo products can typically haveabout 4% air, trapped in tiny bubbles that are not visually discernable.When the shampoo is packed in a typical bottle or pump, over time, thesebubbles combine into larger bubbles due to Laplace pressure. Theselarger bottles will ultimately rise to the headspace if the liquidbeauty care product's stress is not high enough to support the densitydifference between air and liquid. So even if the liquid beauty careproduct is packed in a bottle without any visible bubbles, a headspacecan form within 24 to 48 hours. Increasing the liquid beauty productyield stress can stop bubbles migrating from small to larger bubbles andto the headspace, however a product with high yield stress can havelower acceptance with consumers due to lower spreadability and difficultdispensing.

It was found that when the headspace was eliminated (e.g. either byoverfilling and/or using an insert), an overcap could be screwed orsnapped onto the neck of the bottle to cause a slight over-pressure,that stopped trapped bubbles from migrating without compromising yieldstress of the shampoo composition. When a user is ready to dispense theshampoo composition, they can remove the overcap and pour the shampooproduct into their hand, remove the overcap and insert a pump, or insome instances the overcap can have a pierceable membrane and the usercan punch through the membrane with the pump's dip tube.

It was found that the aesthetic design of the packaged shampoo productcan stay substantially intact following sequence number 1-5 of the ISTA®6A Ship Test (6-Amazon.com-Over Boxing, April 2018 using the ASTM setupfor all tests). As used herein, substantially intact can mean a humanviewer cannot visually discern one or more large areas where thesuspended design is disturbed with the unaided eye (excepting standardcorrective lenses adapted to compensate for near-sightedness,farsightedness, or astigmatism, or other corrected vision) in lightingat least equal to the illumination of a standard 100-watt incandescentwhite light bulb at a distance of approximately 1 foot (0.30 m). In someexamples, the pattern disruption can be assessed by a taking a crosssection of the liquid beauty product and determining what % of the crosssection is disrupted. Less than 10% of the area of the cross section canbe disrupted, alternatively less than 7%, alternatively less than 5%,alternatively less than 3%, and alternatively less than 1%.

Benefit Phase

The benefit phase can include a gel network that can contain one or morefatty alcohols. The gel network can provide conditioning benefits. Asused herein, the term “gel network” refers to a lamellar or vesicularsolid crystalline phase which comprises at least one fatty alcohol asspecified below, at least one secondary surfactant and/or fatty acid asspecified below, and water and/or other suitable solvents. The lamellaror vesicular phase comprises bi-layers made up of a first layercomprising the fatty alcohol and/or fatty acid and the secondarysurfactant and/or fatty acid and alternating with a second layercomprising the water or other suitable solvent. In another example, thegel network can include at least one fatty acid, at least one secondarysurfactant, and water and/or other suitable solvents. The term “solidcrystalline”, as used herein, refers to the structure of the lamellar orvesicular phase which forms at a temperature below the melt transitiontemperature of the layer in the gel network comprising the one or morefatty alcohols.

The multiphase shampoo compositions can include benefit phase that canbe present in an amount of from about 1% to about 90%, alternativelyfrom about 2% to about 50%, alternatively from about 5% to about 40%,alternatively from about 7% to about 30%, alternatively from about 10%to about 25%, by weight of the shampoo composition. The benefit phasecan have a transmission of less than 55%, alternatively less than 50%,alternatively less than 40%, alternatively less than 30%, andalternatively less than 25%, as measured by the Light TransmittanceMethod described hereafter. In some examples, the benefit phase can besubstantially free of a structurant. In other examples, the benefitphase can be free of cationic surfactant and/or anionic surfactant.

The gel network as described herein can be prepared as a separatepre-mix, which, after being cooled, is combined with the cleansing phaseas a visually discrete phase. Preparation of the gel network componentis discussed in more detail below as well as in the Examples.

The cooled and pre-formed gel network component subsequently is added tothe other components of the shampoo composition, including the detersivesurfactant component. While not intending to be limited by theory, it isbelieved that incorporation of the cooled and pre-formed gel networkcomponent with the detersive surfactant and other components of theshampoo composition allows the formation of a substantially equilibratedlamellar dispersion (“ELD”) in the final shampoo composition. The ELD isa dispersed lamellar or vesicular phase resulting from the pre-formedgel network component substantially equilibrating with the detersivesurfactants, water, and other optional components, such as salts, whichmay be present in the shampoo composition. This equilibration occursupon incorporation of the pre-formed gel network component with theother components of the shampoo composition and is effectively completewithin about 24 hours after making Shampoo compositions in which the ELDis formed provide hair with improved wet and dry conditioning benefits.

For purposes of clarification, as used herein, the term “ELD” refers tothe same component of the shampoo compositions of the present inventionas the phrase “gel network phase”.

The presence of the gel network in the pre-mix and in the final shampoocomposition in the form of the ELD can be confirmed by means known toone of skill in the art, such as X-ray analysis, optical microscopy,electron microscopy, and differential scanning calorimetry. A method ofdifferential scanning calorimetry is described below. For methods ofX-ray analysis, see U.S. 2006/0024256 A1.

The scale size of the gel network phase in the shampoo composition(i.e., the ELD) can range from about 10 nm to about 500 nm. The scalesize of the gel network phase in the shampoo composition can range fromabout 0.5 μm to about 10 μm. Alternatively, the scale size of the gelnetwork phase in the shampoo composition can range from about 10 μm toabout 150 μm.

The scale size distribution of the gel network phase in the shampoocomposition may be measured with a laser light scattering technique,using a Horiba model LA 910 Laser Scattering Particle Size DistributionAnalyzer (Horiba Instruments, Inc. Irvine Calif., USA). The scale sizedistribution in a shampoo composition of the present invention may bemeasured by combining 1.75 g of the shampoo composition with 30 mL of 3%NH₄Cl, 20 mL of 2% Na₂HPO₄.7H₂O, and 10 mL of 1% laureth-7 to form amixture. This mixture is then stirred for 5 minutes. As appropriate forthe individual Horiba instrument being used, samples in the range of 1to 40 mL are taken and then injected into the Horiba instrument, whichcontains 75 mL of 3% NH₄Cl, 50 mL of 2% Na₂HPO₄.7H₂O, and 25 mL of 1%laureth-7, until the Horiba instrument reading is between 88-92% T,which is needed for the scale size measurement. Once this is achieved, ameasurement is taken after 2 minutes of circulation through the Horibainstrument to provide the scale size measurement. A subsequentmeasurement is taken using a sample of the shampoo composition which hasbeen heated above the melt transition temperature of all fatty materialspresent in the shampoo composition, such that the gel network componentis melted. This subsequent measurement allows a scale size distributionto be taken of all of the remaining materials in the shampoo, which thencan be compared to the scale size distribution of the first sample andassist in the analysis.

The gel network component of the present invention may also comprise asecondary surfactant. As used herein, “secondary surfactant” refers toone or more surfactants which are combined with the fatty alcohol andwater to form the gel network of the present invention as a pre-mixseparate from the other components of the shampoo composition. Thesecondary surfactant is separate from and in addition to the detersivesurfactant component of the cleansing phase. However, the secondarysurfactant may be the same or different type of surfactant orsurfactants as that or those selected for the detersive surfactantcomponent described above.

The benefit phase of the present invention comprise secondary surfactantas part of the pre-formed gel network phase in an amount from about0.01% to about 15%, alternatively, about 0.5% to about 12%,alternatively from about 0.7% to about 10%, and alternatively from about1% to about 6%, by weight of the benefit phase.

Suitable secondary surfactants include anionic, zwitterionic,amphoteric, cationic, and nonionic surfactants. The secondary surfactantmay be selected from anionic, cationic, and nonionic surfactants, andmixtures thereof. For additional discussion of secondary surfactantswhich are suitable for use in the present invention, see U.S.2006/0024256 A1.

Additionally, certain secondary surfactants which have a hydrophobictail group with a chain length of from about 16 to about 22 carbonatoms. For such secondary surfactants, the hydrophobic tail group may bealkyl, alkenyl (containing up to 3 double bonds), alkyl aromatic, orbranched alkyl. the secondary surfactant may be present in the gelnetwork component relative to the fatty alcohol at a weight ratio fromabout 1:5 to about 5:1. SLE1S may be particularly useful as SLE1S is avery efficient surfactant which foams well. In a shampoo compositionwith high levels of conditioning actives, SLE1S may further provideenhanced lather and cleaning.

Mixtures of more than one surfactant of the above specified types may beused for the secondary surfactant of the present invention.

Examples of gel network premixes may be found in U.S. Pat. No. 8,361,448and US Pub. No. 2017/0367955, which are hereby incorporated byreference.

The fatty acid can include short chain saturated fattyacids such as capric acid and caprylic acid. Without being limited bytheory, it is believed that the unsaturated part of the fatty acid ofalcohol or the branched part of the fatty acid or alcohol acts to“disorder” the surfactant hydrophobic chains and induce formation oflamellar phase. Examples of suitable liquid fatty acids can includeoleic acid, isostearic acid, linoleic acid, linolenic acid, ricinoleicacid, elaidic acid, arichidonic acid, myristoleic acid, palmitoleicacid, and mixtures thereof. Examples of suitable ester derivatives caninclude propylene glycol isostearate, propylene glycol oleate, glycerylisostearate, glyceryl oleate, polyglyceryl diisostearate and mixturesthereof.

In some examples, the cleansing phase can besubstantially free of any cationic deposition polymer or level thereofthat could make the composition appear hazy or cloudy to a human viewerwith the unaided eye (e.g. Polyquaternium-6). The cationic depositionpolymer can be added at a level from about 0.1% to about 15%, preferablyfrom 0.5% to about 8%, more preferably from about 1% to about 5%, byweight of the benefit phase, cleansing phase, or shampoo composition ofthe cationic deposition polymer.

A shampoo composition can include a cationic polymer to allow formationof a coacervate.

As used herein, the term“cationic galactomannan” refers to a galactomannan polymer to which acationic group is added. The term “amphoteric galactomannan” refers to agalactomannan polymer to which a cationic group and an anionic group areadded such that the polymer has a net positive charge.

Galactomannan polymers can be present in the endosperm of seeds of theLeguminosae family Galactomannan polymers are made up of a combinationof mannose monomers and galactose monomers. The galactomannan moleculeis a straight chain mannan branched at regular intervals with singlemembered galactose units on specific mannose units. The mannose unitsare linked to each other by means of β(1-4) glycosidic linkages. Thegalactose branching arises by way of an α(1-6) linkage. The ratio ofmannose monomers to galactose monomers varies according to the speciesof the plant and can be affected by climate. Non Guar Galactomannanpolymer derivatives can have a ratio of mannose to galactose of greaterthan 2:1 on a monomer to monomer basis. Suitable ratios of mannose togalactose can also be greater than 3:1 or greater than 4:1. Analysis ofmannose to galactose ratios is well known in the art and is typicallybased on the measurement of the galactose content.

The degreeof substitution of the cationic groups onto the galactomannan structurecan be sufficient to provide the requisite cationic charge density.

A galactomannan polymer derivative can be a cationic derivative of thenon-guar galactomannan polymer, which is obtained by reaction betweenthe hydroxyl groups of the polygalactomannan polymer and reactivequaternary ammonium compounds. Suitable quaternary ammonium compoundsfor use in forming the cationic galactomannan polymer derivativesinclude those conforming to the general Formulas II to VI, as definedabove.

Cationic non-guar galactomannan polymer derivatives formed from thereagents described above can be represented by the general Formula VII:

wherein R is the gum. The cationic galactomannan derivative can be a gumhydroxypropyltrimethylammonium chloride, which can be more specificallyrepresented by the general Formula VIII:

Cationically modified starch polymers can have a charge density of fromabout 0.2 meq/g to about 5 meq/g, and from about 0.2 meq/g to about 2meq/g. The chemical modification to obtain such a charge density caninclude the addition of amino and/or ammonium groups into the starchmolecules. Non-limiting examples of such ammonium groups can includesubstituents such as hydroxypropyl trimmonium chloride,trimethylhydroxypropyl ammonium chloride, dimethylstearylhydroxypropylammonium chloride, and dimethyldodecylhydroxypropyl ammonium chloride.Further details are described in Solarek, D. B., Cationic Starches inModified Starches: Properties and Uses, Wurzburg, O. B., Ed., CRC Press,Inc., Boca Raton, Fla. 1986, pp 113-125 which is hereby incorporated byreference. The cationic groups can be added to the starch prior todegradation to a smaller molecular weight or the cationic groups may beadded after such modification.

A cationically modified starch polymer can have a degree of substitutionof a cationic group from about 0.2 to about 2.5. As used herein, the“degree of substitution” of the cationically modified starch polymers isan average measure of the number of hydroxyl groups on eachanhydroglucose unit which is derivatized by substituent groups. Sinceeach anhydroglucose unit has three potential hydroxyl groups availablefor substitution, the maximum possible degree of substitution is 3. Thedegree of substitution is expressed as the number of moles ofsubstituent groups per mole of anhydroglucose unit, on a molar averagebasis. The degree of substitution can be determined using proton nuclearmagnetic resonance spectroscopy (“¹H NMR”) methods well known in theart. Suitable ¹H NMR techniques include those described in “Observationon NMR Spectra of Starches in Dimethyl Sulfoxide, Iodine-Complexing, andSolvating in Water-Dimethyl Sulfoxide”, Qin-Ji Peng and Arthur S.Perlin, Carbohydrate Research, 160 (1987), 57-72; and “An Approach tothe Structural Analysis of Oligosaccharides by NMR Spectroscopy”, J.Howard Bradbury and J. Grant Collins, Carbohydrate Research, 71, (1979),15-25.

Cationically modified starch polymers arecationic corn starch and cationic tapioca.

The starch, prior to degradation or after modification to a smallermolecular weight, can include one or more additional modifications. Forexample, these modifications may include cross-linking, stabilizationreactions, phosphorylations, and hydrolyzations. Stabilization reactionscan include alkylation and esterification.

The starch can be readily soluble in water and can form a substantiallytranslucent solution in water. The transparency of the composition ismeasured by Ultra-Violet/Visible (“UV/VIS”) spectrophotometry, whichdetermines the absorption or transmission of UV/VIS light by a sample,using a Gretag Macbeth Colorimeter Color. A light wavelength of 600 nmhas been shown to be adequate for characterizing the degree of clarityof shampoo compositions.

The cationic polymer described herein can also aid in repairing damagedhair, particularly chemically treated hair by providing a surrogatehydrophobic F-layer. The microscopically thin F-layer provides naturalweatherproofing, while helping to seal in moisture and prevent furtherdamage. Chemical treatments damage the hair cuticle and strip away itsprotective F-layer. As the F-layer is stripped away, the hair becomesincreasingly hydrophilic. It has been found that when lyotropic liquidcrystals are applied to chemically treated hair, the hair becomes morehydrophobic and more virgin-like, in both look and feel. Without beinglimited to any theory, it is believed that the lyotropic liquid crystalcomplex creates a hydrophobic layer or film, which coats the hair fibersand protects the hair, much like the natural F-layer protects the hair.The hydrophobic layer can return the hair to a generally virgin-like,healthier state. Lyotropic liquid crystals are formed by combining thesynthetic cationic polymers described herein with the aforementionedanionic detersive surfactant component of the shampoo composition. Thesynthetic cationic polymer has a relatively high charge density. Itshould be noted that some synthetic polymers having a relatively highcationic charge density do not form lyotropic liquid crystals, primarilydue to their abnormal linear charge densities.

Test Methods Hair Wet Feel Friction Measurement (Final Rinse Frictionand Initial Rinse Friction)

A switch of 4 grams general population hair at 8 inches length is usedfor the measurement. Water temperature is set at 100° F., hardness is 7grain per gallon, and flow rate is 1.6 liter per minute. For shampoos inliquid form, 0.2 ml of a liquid shampoo is applied on the hair switch ina zigzag pattern uniformly to cover the entire hair length, using asyringe. For shampoo in aerosol foam form, foam shampoo is dispensed toa weighing pan on a balance. 0.2 grams of foam shampoo is taken out fromweighing pan and applied on the hair switch uniformly to cover theentire hair length via a spatula. The hair switch is then 1st latheredfor 30 seconds, rinse with water for 30 seconds, and 2nd lathered for 30seconds. Water flow rate is then reduced to 0.2 liter per minute. Thehair switch is sandwiched with a clamp under 1800 gram of force andpulled through the entire length while the water is running at the lowflow rate. The pull time is 30 second. Friction is measured with afriction analyzer with a load cell of 5 kg. Repeat the pull under rinsefor total of 21 times. Total 21 friction values are collected. The finalrinse friction is the average friction of the last 7 points and initialrinse friction is the average of the initial 7 points. The delta finalto initial is calculated by subtracting the final rinse friction fromthe initial rinse friction.

Light Transmittance

% T can be measured using Ultra-Violet/Visible (UV/VI) spectrophotometrywhich determines the transmission of UV/VIS light through a sample. Alight wavelength of 600 nm has been shown to be adequate forcharacterizing the degree of light transmittance through a sample.Typically, it is best to follow the specific instructions relating tothe specific spectrophotometer being used. In general, the procedure formeasuring percent transmittance starts by setting the spectrophotometerto 600 nm. Then a calibration “blank” is run to calibrate the readout to100 percent transmittance. A single test sample is then placed in acuvette designed to fit the specific spectrophotometer and care is takento insure no air bubbles are within the sample before the % T ismeasured by the spectrophotometer at 600 nm.

EXAMPLES

The shampoo compositions illustrated in the following Examplesillustrate specific embodiments of the shampoo compositions of thepresent invention but are not intended to be limiting thereof. It willbe appreciated that other modifications of the present invention withinthe skill of those in the shampoo formulation art can be undertakenwithout departing from the spirit and scope of this invention. Allexemplified amounts are listed as weight percent's and exclude minormaterials such as diluents, preservatives, color solutions, imageryingredients, botanicals, and so forth, unless otherwise specified. Allpercentages are based on weight unless otherwise specified.

The exemplified embodiments can provide cleansing of hair or skin,enhanced hair strength benefits (measured as fatty amphiphilepenetration into the hair fiber) and improved conditioning andvolumizing benefits to the hair. Additionally, in one embodiment of thepresent invention, where the cleansing phase is visibly clear and thebenefit phase is opaque, these visual cues are intuitive to the consumerin better connoting the cleaning and conditioning benefits associatedwith the respective product phases within the multiphase shampoo.

The shampoo compositions illustrated in the following Examples areprepared by conventional formulation and mixing methods. The gel networkbenefit phase was prepared as follows. The water is heated to about 74°C. and the fatty compound and secondary surfactant (e.g. Sodium LaurethSulfate) are added to it. After incorporation, this mixture is passedthrough a mill and then cooled (e.g. via heat exchanger) to about 32° C.As a result of this cooling step, the fatty alcohol, the secondarysurfactant, and the water form a crystalline gel network.

The multiphase shampoo composition can be made by using a piston fillerthat can accommodate two or more individual product streams duringfilling. The individual streams can form the aesthetic design in thefinal shampoo compositions. During filling, special care was taken tominimize air entrapment into the cleansing phase during filling intobottles or other suitable primary packaging. In some examples, bottlescan be overfilled using the cleansing phase only, ensuring that anyremaining headspace would be displaced/purged from the bottle duringpump insertion. In some instances, the bottle was capped with a pumpthat was carefully placed to minimize displacement of the aestheticdesign during filling.
